SA2  R15 (System Architecture)

Baseline NR functionality for eMBB & URLLC

SA2  R16 (System Architecture) 5G phase 2

SA2  R17 (System Architecture)

Expand market reach of 5G: Satellite, IoT, Public Safety and MCS (Mission Critical Services), Edge Computing & Interactive Cloud Services,  UAS (unmanned Aerial Systems), 

Addtional Req of mobile operators and verticals: Enhancement, Performance & effeiciency improvement, targeting industrial, V2X, mMTC, eMBB, N/w slicing and IAB ( Integrated Access Backhaul) 

Edge Networking 

• Since R15.uplink classifier or branching point

• 3 connectivity models

1. distributed anchor point

2. session breakout

3. multiple PDU session

• discovery of edge application server 
• N/w info. provisioning to local applications with low latency. E,g, N/w congestion, 
• Seamless edge relocation
• 3GPP application layer architecture support
• DNAI based (I-)SMF selection

By SA2 and SA6 both. Complementary solution. 

SNPN (Standalone Non-Public Network)

R17:

• New Functions
• Credential Holder
• NSS-AAF (Network Slice Specific Authentication and Authorization Function. )
• UE onboarding & provisioning
• IMS voice
• Emergency Service
